Abstract:

Common carp fish (Cyprinus carpio Linnaeus, 1758) were exposed to varying concentrations of waterborne cadmium
(10, 50 and 100 ppb) during 30, 60 and 90 days, respectively. At the end of each experiment time, the influence of cadmium
on fish growth parameters including total length (TL) and weight (W) were measured and its accumulation in muscles was
also determined. Data obtained showed that although growth rate of fish in all cadmium treatments were lower than control
group, this differences was not significant statistically (P>0.05). Our finding related to cadmium accumulation indicated that
exposure to cadmium as cadmium chloride for 30, 60 and 90 days lead to a significant increase (P<0.05) in cadmium
concentrations in the fish muscles. Accumulation of cadmium in muscles has been elevated with increasing in concentration
and duration of cadmium exposures. Therefore the maximum accumulation has been observed in third treatment (i.e. 100 ppb
for dissolved cadmium) after 90 days of exposure. Bioconcentration factors (BF) of cadmium for fish muscles were also
calculated for understanding the rate of cadmium accumulation. Inverse relationships were therefore observed between BF
and water cadmium concentration. In other word, the maximum accumulation rate has been detected at lower cadmium
concentration.
